“…Most Listeria species are susceptible to all antibiotics except cephalosporins and fosfomycin, to which they are naturally resistant [8]. However, increasing reports of Listeria strains isolated from various sources that are resistant to penicillin, ampicillin, tetracycline, streptomycin, clindamycin, and even oxacillin and vancomycin represent a major public health concern [9][10][11].…”

Introduction: Listeria species are susceptible to most antibiotics. However, over the last decade, increasing reports of multidrug-resistant Listeria spp. from various sources have prompted public health concerns. The objective of this study was to characterize the antibiotic susceptibility of Listeria spp. and the genetic mechanisms that confer resistance. Methodology: Forty-six Listeria spp. isolates were studied, and their minimal inhibitory concentrations of antibiotics were determined by microdilution using Sensititre standard susceptibility MIC plates. The isolates were screened for the presence of gyrA, parC, lde, lsa(A), lnu(A), and mprF by PCR, and the amplified genes were sequenced. Results: All isolates were susceptible to penicillin, ampicillin, tetracycline, erythromycin, and carbapenems. Resistance to clindamycin, daptomycin, and oxacillin was found among L. monocytogenes and L. innocua, and all species possessed at least intermediate resistance to fluoroquinolones. GyrA, parC, and mprF were detected in all isolates; however, mutations were found only in gyrA sequences. A high daptomycin MIC, as reported previously, was observed, suggesting an intrinsic resistance of Listeria spp. to daptomycin. Conclusions: These results are consistent with reports of emerging resistance in Listeria spp. and emphasize the need for further genotypic characterization of antibiotic resistance in this genus.

“…As regards L. monocytogenes, the isolates were found resistant to nalidixic acid and ceftriaxone, and partly resistant to clindamycin and cefotaxime. Resistance to "modern" cephalosporins and to nalidixic acid was expected because it is considered an innate resistance (Troxler et al, 2000). In regard to clindamycin, according to Chen et al (2010), its effect to Listeria species is a controversial issue as some studies suggested its sensitivity whereas another study reported high incidence of resistance.…”

ABSTRACT. Souvlaki is a popular Greek meat product consisting of small chunks or cubes of pork threaded on a small wooden or metal skewer. In the present study, 105 samples of raw pork souvlaki obtained from retail shops in Thessaloniki (Northern Greece) were screened for the incidence of Salmonella, Listeria, and Campylobacter and their susceptibility to various antimicrobial agents; serotyping of the isolates was also performed. Of the samples tested, 1.9% were positive for Salmonella and yielded 3 serovars (S. SaintPaul, S. Fyris and S. Typhimurium); 31.4% proved positive for Listeria spp. with 6.7% yielding L. monocytogenes isolates belonged to molecular serogroups 2 (serotypes 1/2c and 3c) and 4 ( serotypes 4b, 4d, and 4e). Campylobacter spp. were not detected in any of the samples tested. The antimicrobial susceptibility to various antimicrobial agents of 11 Salmonella strains and 7 L. monocytogenes strains was also determined by disc diffusion method. Salmonella spp. were susceptible to a panel of 12 antibiotics but displayed intermediate resistance to tetracycline. L. monocytogenes isolates were resistant to nalidixic acid and ceftriaxone, partly resistant to clindamycin and cefotaxime, but sensitive to all antibiotics commonly used in veterinary and human listeriosis. Our findings indicate that souvlaki could be a potential vehicle of food borne infections due to strains of L. monocytogenes and Salmonella spp. in the case of inadequate thermal processing. In addition, good hygienic practices must be applied to avoid cross-contamination during preparation or handling of the product. Keywords

“…Cui et al (2005) synthesized a series of oxazolidinones and compared their activities against a panel of gram-positive bacteria with linezolid. Troxler et al (2000) described a database on susceptibility of Listeria species strains to a wide range of antibiotics. Scortti et al (2006) studied fosfomycin susceptibility against L. monocytogenes and found resistant in vitro, although they are in fact susceptible to the antibiotics during infection.…”

Oxazolidinone, a new class of antimicrobial agents is active against various Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcus epidermidis (MRSE), penicillin-resistant Streptococcus pneumoniae (PRSP) and vancomycin-resistant Enterococci (VRE). Sensitivity of Oxazolidinone Linezolid was studied against pathogenic microorganism Listeria ivanovii and Minimum Inhibitory Concentration (MIC) determined by broth dilution method and Hi-Comb method was 10 µg/ml. Morphological alterations on Listeria ivanovii cell surface were seen by Scanning Electron Microscopy (SEM) after treatment with Linezolid. Inhibition on the activity of dehydrogenases of organism by Linezolid was also studied in the present study.
